sired'adjustedlposition by means of notched links 58 carried by brackets secured to the upper edge of the blade and ooperating of the main frame with pins V59 carried by of yoke 43.

Slidablyv moun ed-upon the cross bar 10 10 is a bracket 61 which carries a gravity latch pin 62 adapted to enter any one .of a series of notches 63 formed in a blade 64 carried b the cross bar 10. Extended through the bracket 61, beneath the lower end ofthe latch pin 62 is .an operating arm or lever 65 havlngy a bifurcated inner end 66 pivoted at 67 to the rear end of frame 46. The lever 65 passes through the depending arms an opening 71 in the bracket 61. This open' ing at its lower side is provided with shoulders 72 beneath one of which the lever 65. will normally. lie, so that it will not accidentally engage the gravity latch 62 so as to withdraw it from the desired notch 63 and plate 64 (see Fig. 11).

The forward end-of frame 46 is pivoted upon. an inclined axis at 81 to cross bar 13.,

Slidably mounted upon the cross -bar 13 is a bracket 82.'Y Pivoted upon a vertical axis, at 83, to bracket 82 isthe 'front axle structure 84, said front axle structure being carried by suitable supporting wheels 85. "The structure 84 also carries a suitable tongue 86. Any suitable means may be provided to hold the bracket 82 in any desired position of adjustment upon bar ,1 3. In the form shown in the drawings, we have provided the upper edge of bar 13 with a plurality of notches 87 adapted to receive a latch pin 88 pivoted at 89 on bracket 82. The pivotpin-` .89 may be conveniently carried by a clamplng plate 91 between which and the main vbody of the bracket 82, the upper edge of bar 13 may be firmly clamped by.-

the cross means of clamping bolts 93.

In operation, the blade 41 may be'set at.

any desired angle to the line of a road by swinging the -same upon pivot 45 and also.

by, swinging the bladecarrying frame 46 upon its forward pivot. In order to reversethe road angle of the blade, links 58 are disconnected from pins 59, theA blade turneddown' fiat. upon the ground, and latch 47 wlthdrawn. Thmeupom'by lowering arms 53 to the position shown in Fi 1,`t he en- I 'tire main frame ofthe machine" may be lifted from the' ground, the weight being supported upon the' blade. resting upon the turned as a whole that therear supportground. Thereup, the machine may be veo ing wheels 21 will ass over the blade in the manner illustrated n Fig. 1, and when this has been accomplished, the blade carrying frame 46 may 4be .shifted about the pivot 45 so as to reverse Ithe road an le of the blade as lndicated indotted lines 1n Fig. 4. The mold board being placed between the rear wheels places practically` all the side draft,

.the forward. end of the mold board and due to .the` angular. position of the mold board, upon the rear wheels, so that these rear wheels are the only ones which need to be adjusted toa vertical angle in order' to take care of the side draft. When it is desired to move dirtfrom the extremey side of Athe road ltoward the other side it is necesl sary to provide some means by`which the 'horses may travel alonglines separated from the windrow or loose dirt engaged by therefore, in order to obtain' a maximum'V movement of dirt, the parts are adjusted as-v shown in Fig. 5, the front axle 'structure bein shifted 1n the directionopposit'e to the so that the adshifting of the mold board 'acent front wheel runs to the delivery side ofthe advance end ofthe mold board. This places the horses to the center of the road and projects the forward edge of the mold dirt is tobe moved from the center of the road to one side the parts will be adjusted in the manner showrr'in Fig. 6 thus placing the front axle in such position that the horses will walk. upon the opposite sides of the windrow. It will be understood of course,- that the same relative adjustments may be roduced with the road angle of the mold g oard reversed. It will also be understood that similar adjustment'results can be obtained, although not quite so advantageously, by keeping the front axle fixed relative to the forward end of the main frame and shifting the front end of the mold board lframe 46 transversely, as illustrated .in Fig. 13.

We claim as our invention:
